WMS420 is a professional multi-channel wireless microphone system providing a highly flexible and easy to use solution. The ultra high frequency system is set up within seconds and is equally suitable on stage as well as in locations where a single- or multi channel solution is needed.

The Vocal Set includes a HT420 handheld transmitter featuring a patented state-of-the-art D5 dynamic capsule for well-balanced, powerful sound. This capsule guarantees maximum rejection against feedback, reduced handling noise and the famous AKG sound. The space diversity receiver offers both a microphone level and a line level output.

Transmitters are shipped with charging contacts that enable the use of rechargeable batteries. Moreover the transmitters offer exceptional eight hours of operation time from a single AA size battery, which dramatically reduces the operating costs in day-to-day use.
